Chris -- thanks -- I mounted the netapp on a solaris 2.7 box yesterday and didn't have the problem so I figured it was solaris 9 related.

You mean Solaris 9 (SunOS 5.9), presumably.

Anybody ever see this error?
Not until I did some experiments ... :)
The "Cycle detected" message is apparently (from "strings" output) new in Solaris 9 "du". It seems that it happens whenever one applies "du" to a directory tree in which there are "visible" .snapshot directory entries (i.e. one or more NFS mount points).
Presumably it's getting upset by the duplicate inode numbers appearing in snapshots. Lots of Unix utilities (especially GNUish ones) have had similar problems in the past.
[Of course, it's not unreasonable to take the line that their confusion is quite justified, and that NetApp have a design fault here.]
